Smart Vehicle Door Opening System with Obstruction Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face challenges in judging the sufficiency of parking space when parking near barriers or other cars, leading to potential damage from opening car doors into obstructing objects, especially in narrow spaces.
Innovation Solution
A smart opening system equipped with sensors and processing elements that dynamically alert drivers to insufficient spatial issues and limit door opening angles to prevent impacts, using sensors to detect obstructions and calculate necessary door opening ranges based on vehicle configuration and passenger needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is opened to a larger angle to accommodate different user needs, then the accessibility and ease of operation are improved, but the risk of collision with obstructions increases
Solution Approach 1:
The system performs preliminary detection of obstructions in the door's range of motion before the door is actually opened. Sensors scan the area and the processing element calculates potential collision risks in advance, allowing the system to prepare appropriate responses (warnings or limitations) before the harmful event could occur.
Solution Approach 2:
The system continuously monitors the door's position and the presence of obstructions, providing real-time feedback to the driver through warnings. The system also feedbacks by dynamically adjusting the door's range of motion based on detected conditions, creating a closed-loop control system that adapts to changing environmental factors.
2Reliability
If sensors and processing elements are added to detect obstructions and limit door opening, then the safety and damage prevention are improved, but the device complexity increases
Solution Approach 1:
The sensor system is designed to serve multiple functions: detecting obstructions, determining their type (vehicle vs. other objects), calculating range of motion intersections, and triggering appropriate warnings or limitations. This multi-functionality reduces the need for separate specialized components for each function.
Solution Approach 2:
The processing element autonomously performs calculations to determine whether obstructions intersect with the door's range of motion and automatically issues warnings or adjusts door limits without requiring external intervention or complex mechanical safety devices.

AI summary
A smart opening system is provided. The smart opening system includes a vehicle defining an aperture, a door coupled to the vehicle to assume a first position at which the aperture is closed and multiple second positions at which the aperture is open and to move between the first and second positions, a sensor disposed to sense obstructions surrounding the vehicle and a processing element coupled to the sensor and configured to determine whether any of the obstructions are within a range of motion of the door.
